Q1.
Step 1: Take a square piece of paper. Mark as shown to make the cat’s head and ears. Step 2: Now, cut along the outline and slide the top piece down to align with the larger piece. Step 3: Tape the pieces together. Your wall is ready. Step 4: Now the real fun begins! Trace the outline of the cat pattern on a large piece of paper and make its face.The four steps, as they are drawn in the book.
Answer
Follow the four steps to make one cat tile.
Take a square sheet. On the top edge mark two pointed ears with a dip between them.
Cut along that line. You now have a small top piece and a large bottom piece.
Slide the top piece down to the bottom edge and tape it there.
Trace this new shape on a big sheet and draw eyes, nose and whiskers.
Left: one cat tile. Right: the same tile repeated to make a wall.
Why it happens: Whatever you cut off the top is added back at the bottom. The tile covers just as much space as the square did, so copies of it still fit together.
Q2.
Create more of these tiles. Some ideas to make creative wall patterns are given below.The ideas printed on page 173: a square with a wavy cut, the tile that cut makes, and a wall built from arrow tiles.
Answer
Trace your cat tile again and again to cover a big sheet.
Trace the tile at the top left corner of the sheet.
Slide it sideways by one tile and trace it again, right along the row.
Start the next row directly below, so the ears fit into the dips above.
Colour the cats in two colours, turn by turn.
Cat tiles repeated to make a wall pattern.
Sample answer: I made 12 cat tiles in two colours and covered a full chart paper. As Mini says, the tiles still fit perfectly without any gaps or overlaps.
Why it happens: The bump on one edge of the tile is exactly the same size as the dip on the opposite edge, so one tile slips neatly into the next.
